Right. >Can you let me know the status of this tool? It has been ready to go for quite some time. To make sure that the latest code mods are in the gribdec.tar.Z bundle, I just recut it. You can grab it from the unix/gribdec directory of passworded FTP on our FTP server, ftp.unidata.ucar.edu: <login as 'mcidas'> mkdir gribdec cd gribdec ftp ftp.unidata.ucar.edu <user> umicdas <pass> XXXXXX cd unix/gribdec binary get gribdec.tar.Z quit tar xvf gribdec.tar.Z | tar xvf - <set CC, CFLAGS, FC, and FLAGS to match the environment in which McIDAS was built> make -- or -- make VENDOR=-gcc if use gcc/f2c/mcfc -- or -- make VENDOR=-g77 if use gcc/g77 To run this from the McIDAS account, set your MCPATH to include the directory in which you unpacked gribdec.tar.Z as the first directory in MCPATH. In the example above, this is /home/mcidas/gribdec, so you would redefine MCPATH as follows (C shell syntax): setenv MCPATH /home/mcidas/gribded:$MCPATH At this point you should be able to run gribdec.k (decode GRIB messages into a McIDAS GRID file) or grib2img.k (decode a GRIB message into an image in McIDAS AREA file format). >Thanks! Please let me know if you have any questions on using gribdec.k or have problems doing the build. By the way, Johnson Space Center has been using the code for awhile now, so it has been exercised. Also, there was the issue/possibility of you getting the CONDUIT feed via IDD. We can get you setup if you want this (or portions of the feed as it is a lot of data (1.2 - 1.8 GB/hour)). Later... Tom
